Hypothyroidism is a condition of the thyroid gland, which affects the secretion and function of some hormones (T3, T4, TSH). Treatment for hypothyroidism is based on giving the patient the hormones they cannot make. The drug prescribed is synthetic thyroxine (T4), which is the same as the hormone produced by the thyroid. If the diagnosis of hypothyroidism is correct, the disease is permanent and the treatment chronic.
Hypothyroidism indirectly affects body weight through the fluid retention it causes. But it is a myth that a hypothyroid sufferer cannot lose weight. Body weight is affected ONLY in case of dysregulated thyroid gland. Once regulated by medication, there is no influence on body weight. Even in the case of an unregulated gland, however, the weight gain is relatively small, while there may be difficulty in losing it and it may take a little more time to reach the goal.
However, even in the time period until the diagnosis and regulation of the gland, by changing the eating habits for the better, we can achieve a reduction in our body weight, at least the percentage that is affected by our eating habits. By regulating the gland with medication and continuing to eat properly, the percentage of weight affected by the disease will also decrease.
